Pretty good for the price($480). Supports 1080p/120hz mode and is rated for 8.3ms. Excellent low motion blur and you have a nice little portable projector than handles plenty of resolutions and doesn't break your wallet.

https://www.projectorcentral.com/Optoma-HD27HDR-Review.htm This review mentions rainbows not being that noticeable to that person.

I saw that, but the reviewer seems to use movies to test. Their 120Hz testing seems very limited.

At that 60Hz, you're getting at least a 4x color wheel. It's mechanical, so there are limits to what can be done; by the time we get the refresh up to 120Hz, things are spread (awfully) thin. At that point, it's like the old days.

That is a pretty good review site, but they definitely don't boot up a dozen games on an RTX2080ti and play through at 120fps. I still think a game of Dishonored at 120fps would quickly turn painful.
